Works Great for Large House

  • Expensive Filter

Best Uses

  • Whole house

Comments about ESSICK AIR PRODUCTS AirCare Large Home Evaporative Humidifier (H12400HB):

This unit has worked great for our 2,400 sq. ft. house. The fill bottle could probably be a little larger and must be filled at least once and sometimes twice per day in a large house here in VERY DRY Southern Colorado. The filters are pretty expensive and our hard water means we usually need two per season due to build up on the media. Use an ACE discount coupon to get them at half price! Softer water would probably get longer performance from the filter.

All that said, this unit has performed wonderfully for three years without incident. The auto shut-off is actually pretty convenient. The problem others have mentioned is not with the unit, but with the filters. You have to set an adjustment arm on the filter that holds the shut-off float in place to make sure the float rises and lowers properly. It takes some jiggling to get it right, but it isn't a big deal.

I would recommend to anyone that needs a reliable, whole house humidifier.

Comments about ESSICK AIR PRODUCTS AirCare Large Home Evaporative Humidifier (H12400HB):

Prior Model - different vendor had belt-drive fan with reduced RPM much quieter operation on low (normal) settings. Also, prior model/vendor had dual-tanks which required less filling.

Comments about ESSICK AIR PRODUCTS AirCare Large Home Evaporative Humidifier (H12400HB):

Good air flow and wick and controls. Float for "low water turnoff" sticks. Very hard to get valve on fill tank to work right, Milk colored plastic fill tank, hard to see level of water.

    • Automatic Shutoff Doesn't
    • Auto Refill Doesn't

    Best Uses

      Comments about ESSICK AIR PRODUCTS AirCare Large Home Evaporative Humidifier (H12400HB):

      Our old Essick worked perfectly. This one does not. I have to fill it by hand and the automatic shutoff does not work when it is out of water. The water container does not empty automatically.
